SEED-DRILL.

SPEOIFICATIQN forming part of Letters Patent No. 236,508, dated January11, 1881.

Application filed May 21, 1880.

To all whom it may concern Be it known that we, DEWITT O. NORRIS andALBERT N. NORRIS, both citizens of the United States, residing atBushville, in the county of Bush and State of Indiana, have inventedcertain new and useful Improvements in Side-Draft Seed-Drills, of whichthe following is a specification.

Our invention relates to improvements in side-draft three-hoed drillsfor drilling wheat, rye, oats, or barley; and the objects ofourinvention are. first, to provide the frame of a three-hoed side-draftdrill with a hinged part and a means of adjusting said hinged part,whereby the hoes which are on the adjustable part may be adjusted todrill closer together or wider apart in the row, according to thevarious widths of the rows between the corn second, to provide afeed-cup with a semicircular slit in one of its vertical sides, in whicha curved cut-off operates, and with central holes in both sides toreceive the journals of a non-adjustable feed-wheel, the ends of whichabut against the inner smooth parallel walls of the feed-cup, which haveno cheeks or grooves. These objects we attain by the mechanismillustrated in the accompanying drawings, in which- Figure 1 representsa plan view of the frame of a three-hoed drill with the fcedbox andfeed-cups removed. Fig. 2 is a perspective view of the entire machine.Fig. 3 is a side view of one of the feed cups, showing the semicircularslits in the side for the semicir- Fig. 4 is a vertical cross-section ofthe feed-cup, showing the feed-wheel mounted therein. Fig. 5 is a sideelevation of the feed-cup, showing the opposite side from that shown inFig. 3. Fig. 6 is a top or plan view of three feed-cups and themechanism for operating the feed-wheels, also the devices for regulatingthe amount of grain fed by the feed-wheels. Fig. 7 is a top view of thethree semicircular slides or cut-offs attached to their operating-bar,but detached from the feed-cups. Fig. 8 is a side elevation of Fig. 7,and Fig. 9 is an end view of Fig. 8.

Similar letters refer to similar parts throughout the several views.

The main frame is composed of the two parts A A, the part Ahaving theusual opening or (No model.)

slit A to receive the driving-wheel F, said wheel being mounted in theboxes E E, and provided with the miter-wheels H H, all in the usualmanner. The front standard, F, is also secured in the end of the slit Aand supported by the braces h h, also in the usual manner. The part A ofthe frame is arranged at an angle to the part A, as shown in Fig. 1, andis united to the part A by the plates D D, one above and the other belowthe frame.

The plates D and D are pivoted at c to the frame A, and firmly securedto the part A by thebolts d d. The plates D D are each provided with anarm in which is formed the segment-slotf, in which fits a bolt, 6, andall are arranged so that the part A may be adjusted to the angle shown,or to an angle approaching more to a straight line with the part A, bymeans of which the hoes s 8 8 which are attached to the lower part ofthe part A, may be adjusted so as to drill wide apart or close together.

On the front side of the part A is secured a plate, B, having a seriesof holes, I) b, as shown; and to the front standard, F, is secured theclevis G, with a side projecting arm provided with holes {1, andv aring, G, projecting forward from its front side near its end.

The rod 0 is provided with hooks at each end, which fit into the holes bb of the plateB and into the holes 9 of the clevis G, as shown, by meansof which the part A of the frame may be adjusted open by inserting thehooked end of the rod 0 into the holes I) closer to the inner end of theplate B, thus causing the drills to come more in line one with theother, and drill closer together. By attaching the rod 0 to the clevisclose to the standard F a side draft is provided, and the closer the rod0 is coupled to the standard F the more the drills are carried towardthe right when draft is applied, and vice versa.

The feed-cups P may be of any ordinary form, haviuga semicircular slit,'0, in one side, as shown in Fig. 3, for the semicircular slide t tooperate in. The feed-wheel B may be of any ordinary form, although weprefer the corrugated wheel, as shown. Several of these feed-cups P areattached to the bottom of the feed-box J, and their lower ends insertedin the holes a a a of the adjustable frame A over the hoes s s 8 Thesquare rod or shaftVpasses through all the feed-wheels in the severalcups, and one end of the rod is coupled to the rod I by the universaljoint n m, by means of which and the driving-wheel and its gearing thefeed-wheels R are rotated in the cups.

At the rear side of the feed-box J is secured a metal case, K, the upperpart of which is provided with a graduated rib, k, and the lower part isprovided with a slot, 1', with a recess behind it, in which operates anut, (not shown.) The thumb-screw 0 passes through the hole 1) of theindicator L, also through the slot 1' into the nut (not shown) containedin the recess behind said slot 0*, by means of which the indicator L maybe moved laterally in either direction and made fast at any desiredposition. The lower end of the indicator L is firmly secured to the barW, and to said bar, also, is secured the semicircular slides t t t, bymeans of the arms T T T, which are securely riveted or bolted to saidbar, as shown .in Figs. 7, 8, and 9. The semicircular slides t t t areinserted into their respective semicircular slits v in the feed-cups, asshown in Fig. 6, and the indicator L is made fast to the case K, asbefore described.

The operation of our improved drills is as follows: If it is desired tothrow the drills more to the right, then the rod 0 is hooked into one ofthe holes 9 nearer to the standard F. The draft being on the ring Grthrows the rear end of the drill toward the right. This adjustment isregulated more or less, according to the hole in the clevis in which therod 0 is hooked. If it is desired to drill the furrows nearer together,then the rod 0 is adjusted in the holes I) of the plate B-that is, thenearer the rod 0 is to the inner end of the plate B the more the part Ais straightened out and the closer the furrows are made by the drills.The semicircular slides t t t are operated by the indicator L and rod Wto regulate the amount of grain fed. Thus, if but a small quantity ofgrain is to be planted, the indicator L is moved to the left until theindicator part indicates on the graduated rib 7c the desired amount ofgrain to be fed at each revolution of the driving-wheel F. It isobvious, if more grain is to be fed, that by adjusting the slides t t tfarther out of the cups more grain will be presented to the action ofthe feed-wheels.

It will be observed that the semicircular slides 15 t t fit very snuglyaround that side of the feed-wheel against which the grain ordinarilylies when in the cup, and that the lower edge of the semicircular slidesare in close proximity to the bottom of the cup on the inside, and thatthe upper edge of the slide is above the top of the feed-wheel, so thatthe grain cannot get to the feed-wheel only as it passes by the end ofthe slide, and that the slides can be perfectly adjusted to regulate theflow of grain to the feed-wheels.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In aside-draft seed-drill, the frame A A, hinged by plates D D, thepart A provided with a plate, B, perforated with holes I), the part Aprovided with a standard and side projecting clevis, G, having holes 9between the standard F and the ring G, combined with the rod 0, as andfor the purpose specified.

2. The clevis Gr, having a side projection provided with holes g, and aring or eye, G, at its end, combined with the standard F, rod 0, andframe A A, as and for the purpose specified.

3. The combination, in a side-draft seeddrill, of the side projectingclevis, G G, with holes 9, the frame A, with hinged adjustable part A,the plate B, with holes I), and the rod 0, substantially as described,for the purpose specified.

4. The frame A, with hinged part A, provided with the plate B, havingholes I) 1), combined with the rod O, whereby the part A, with itsdrills, may be adjusted to drill furrows wide apart or close together,substantially as specified.

5. The feed-cup P, having a semicircular slit, v, in one of its verticalsides and central holes to receive the journals of the non-adjustablefeed-wheel, and both its inner vertical walls at the ends of thefeed-wheel formed parallel with each other, with no cheeks or grooves,in combination with the curved cutoff slide t, substantially as and forthe purpose specified.

6. The combination, in an adjustable sidedraft seed-drill, of thefeed-cup 1?, having a semicircular slit in one of its vertical walls,and the inside surfaces of said walls formed straight, without anyannular grooves or checks, the cutoff slide consisting of the curvedpart t, having a ring-bracket projectin g at right angles from one endof the curved part, and further provided with an arm, T, which projectsat right angles to the ring part on the opposite side from that of theslide, but parallel thereto, and the rod W, as shown and described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
